Be it'known that l, Tnoniis F. NOLAN, a c t zen of the L-mted States of America, and a L l 'v' v u resldent' of .\ewiork,.in the county and State ,,of "N ew Y ork, have invented -certain new and useful Improvements in .Plaltens' or Rollers for Type-Writing Machines, of which the following is a specification. Y

ments in. a novelxpla-t-en or'roll'er for t. vpcwrit-. ing machines and the like and the method of making same. r

it is the special object of this invention to provide a platen or roller for typewriting machines which is very cheaply manufactured and may be easily practically any cost.

The invention further consists in the method of lacing or stitchingtogether a piece of felt for thla purpose 'of'formnig. a smooth tube without any seam. This is attained by stitching the felt ina peculiar and novel repaired without manner as will be more fully explained far ther on. The surface ofthe felt is provided with a layer of suitable fabric, preferably of silk which has been saturated with a rubber solution. Whenthe surface of the roller. has been somewhat impaired by continued use the roller istaken out of the machine, the

silk surface removed and a new silk surface is applied easily and quickly.

- The invention. is illustrated in the accompanying drawing in-which Figure 1 is a perspective view of a platen or roller which embodies my invention. Fig. 2 is a plan view of a flat piece of felt showing a few parallel lace stitches not drawn together as yet. Fig. 3 is a plan view of part of said feltpartly' drawn togetherto illustrate the location of the stitches. Fig. 4' is a cross section through the platen, and Fig. 5 is a cross section on line 5,6 of Fig. 21

Similar characters of reference. parts all the figures. 5 g

The platen or roller shown on the drawing is one newly manufactured according to this "invention. It is however understood that both the felt and the silk tube surface may be applied to any existing roller of old consu action. The silk cover alone also may be applied to any roller of old construction and even to the rollers made of hard rubber and. the like when same show impressions. on the surface from continued use.

denote like In Fig.'1 a represents the bearing of the I I; roller adapted to receive the shaft which carl l l l l l hole Z.

' ries an iron front plate 0 of circular shape. A

wooden cylinder 0 is supported by the bearing a in the usual manner, see Fig. 4. The felt is represented by the letter dg The silk cove-1'v is designated by'the letter 8, asshown in Figs' land The enumerated elements platen is composed.

The bearings, shaft, and wooden tube are assembled in the usual'manner. The cylintogether with the shaft e, shown in section in i Fig. -L, are all the elements of 'wh ich the This invention has reference to 1mprove 5 6';

cision is tohide'the stitches. In order to produce a smooth'surface when thefelt is formed into the tube or "cylinder the stitching has to.- bedone in a peculiar manner. The method of stitching which I prefer to call lace stitch- I mg is apparent from Figs. 2.and 3. Asinglc thread is used. The needle is first inserted in the incision f andrun out in the center line of the side gof ,the felt forming a stitch hole 71. The thread is carried over to the otherside & of the felt and the needle ,inserted-directly opposite into the middle of the side and run outtln'ough the, channel-f forming a stitch h'olekL- Now the needle is inserted in the same incision f a little distance farther in and'run again through the center of theside of-the felt forming av stitch- Tl'iesthread is carried over to the long side g of'the felt and the needle run through. the center line and the channel f whereby the two threads are parallel to each other, The stitch hole m is thus formed. The needle is inserted somewhat farther in in the incision f and forced through the center line of theside as above described and the thread again carried-over to the other side'wlicreby a continuous row of parallel stitches are produced. When the entire. length of the felt has thus been stitched same is gradually drawn together as indicated in Fig. 3 and finally-a cylinder or tube is formed. From this peculiar method of .producing parallel lace stitches it is apparent that a tube isfo'rmed without showing any seam when finished andle'aving an entirely smooth surface without any edge on the line keys on the. felt cylinder with the silk surface saturated with rubber which also fills thepores does not produce any impressions on so pliable a surface and the roller lasts a long tnne. However as above stated if con sidcred necessary the silk surfaceinay be peeled off and a new layer of silk ut on in a short time and i at a ,very sma l expense. Furthermore the weight of the novel platen has been greatly reduced and is about one half of .the platens of former constructions. This saves the wear and tear on the inachine and the felt and silk also act as sound deadening materials. j

Having thus described my invention I claim as new and desire to secure by Letters Patent: v

1. A platen or roller for typewriting inachines comprising a wooden roller body with bearing and shaft, a tube or cylinderef felt made in one piece and forming a tube by parallel laced stitches concealed within the material, and a layer ofsuitable fabric saturated in a rubber solution applied to the outer surface of the felt cylinder.

' A platen or roller for typewriting machines comprising a wooden roller body with bcarii'ig and shaft, a tube or cylinder of felt inade in'on'e piece and forming a tube by parallellaced stitches concealed within the mate rial, and a layer of silk saturated in a rubber solution applied to the outer surface of the felt cylinder.

3. The method of producing a platen or roller fortypewritingr machines consisting in preparing a felt cylinder by cuttingthe felt into an oblongof the desired size, making an incision along the longitudinal sides and pro; dncing parallel lace stitches by inscrtii'ig the needlein one incision, drawing it out in the center line of the one side, carrying the thread over, running it through the center line of the other long side and the second incision, passing the needlc through the incision a little farther in and out in the middle of this long side and carrying the thread over, etc, whereby parallel lace stitches result, drawn]; the 'lace stitches together until a tube or cylinder is formed, mounting the tube on the roller body, and applying; a lay r of silk sat;

urated in rubber solution on the top sin-:55 face of the felt cylinder.
